Detailed Analysis:

1. Interpretation of "PVC Conduit Pipes and Fittings":
The core issue revolves around the interpretation of the term "PVC conduit pipes and fittings" as per entry 136 of the First Schedule to the Tamil Nadu General Sales Tax Act, 1959. The court needed to determine whether PVC water pipes could be classified under this entry for the assessment year 1976-77.

2. Differentiation Between PVC Water Pipes and PVC Conduit Pipes:
The petitioners argued that PVC water pipes conforming to IS 4985 are technically and commercially different from PVC conduit pipes conforming to IS 2509. They emphasized that these products have distinct properties, specifications, and uses as evidenced by Indian Standards Institution classifications. PVC water pipes are designed for potable water supply, whereas PVC conduit pipes are intended for electrical installations.

3. Applicability of Dictionary Meanings:
The petitioners contended that relying solely on dictionary meanings is misleading. They cited precedents such as "Collector of Central Excise v. Krishna Carbon Paper Co." and "Commissioner of Sales Tax v. S.N. Brothers," arguing that dictionary meanings should not override the technical and commercial understanding of the goods. The court acknowledged that while dictionary meanings can be considered, they should not be the sole factor in classification decisions.

4. Commercial and Technical Distinctions:
The court examined various technical documents and standards, including specifications from the Indian Standards Institution. It was noted that PVC water pipes and PVC conduit pipes differ in chemical composition, dimensions, manufacturing methods, usage, and pricing. The court highlighted that PVC conduit pipes are used for electrical installations, while rigid PVC pipes are used for carrying water or other fluids. The court also reviewed invoices and customer orders, which clearly distinguished between the two types of pipes.

5. Legislative Amendments:
The court considered the legislative amendments to entry 136, effective from January 1, 1985, which expanded the classification to include all varieties of PVC pipes, tubes, and fittings. This amendment indicated a broader interpretation post-1985, but for the assessment year 1976-77, the narrower interpretation applied.

Conclusion:
The court concluded that PVC water pipes and PVC conduit pipes are distinct goods with different technical and commercial properties. The Tribunal's reliance on dictionary meanings was deemed inappropriate. The court set aside the Tribunal's order, ruling that PVC water pipes should not be classified under entry 136 of the First Schedule to the Tamil Nadu General Sales Tax Act, 1959, for the assessment year in question. The revision petition was allowed, and no costs were imposed.
